designed to observe a baseline heart rate and blood pressure and to examine various modifications of the two. This experiment utilized both the BiopacPro and PhysioEx computer programs. The PhysioEx program was used to simulate a heart rate and modifications to it. The BiopacPro program was used to monitor a volunteer’s blood pressure; while PhysioEx was again used to monitor the modifications to it. Heart rate was shown to decrease as temperature decreases‚ increase in the presence of epinephrine‚ and

List the substrate and the subunit product of amylase. _starch & maltose respectively__ 2. What effect did boiling and freezing have on enzyme activity? Why? How well did the results compare with your prediction?__Boiling caused amylase to be denatured‚ thus inactivating the enzyme. Freezing has no effect. The function of an enzyme is directly related
